Generic markup converter

I'm a big fan of Markdown, and often set up models to automatically apply it to certain fields before saving. But that's not really flexible, because if I then distribute the code someone else might want to use reStructuredText or Textile or whatever, and then they have to hack my code. So here's a function which looks for a setting called `MARKUP_FILTER` and, based on what it finds there (see the docstring for what it looks at), chooses a text-to-HTML conversion function and applies it to a piece of text. Since Textile, Markdown and reStructuredText all support various useful options, it has the ability to pick up arbitrary keyword arguments and pass them through.

Get current user without a request object

Mechanism to obtain a `request.user` object without the `request` object itself. Requires `LocalUserMiddleware` in `MIDDLEWARE_CLASSES` settings variable. **Important**: works under assumption that within a web server each request is handled by a separate thread (as for example in the Apache HTTP server). **Beware**: [security threat](http://code.djangoproject.com/wiki/CookBookThreadlocalsAndUser), although ["thread locals only appears to be a security threat if a system has already been seriously compromised, at which point there'd be easier attacks to execute"](http://groups.google.com/group/django-users/browse_thread/thread/e7af359d7d183e04). **Dev note**: works fine with one-threaded Django's development server, each request resets current user; no worries 'bout many media requests - they won't (at least shouldn't) be using Django on the production server. **Ref**: originally found in the gatekeeper app.

Online boolean switch in the admin list

You can switch boolean fields in the admin without editing objects Usage: ` class News(models.Model): # ... pub = models.BooleanField(_('publication'),default=True) # ... pub_switch = boolean_switch(pub) class Admin: list_display = ('id', 'pub_switch') ` Thanks for [svetlyak](http://www.djangosnippets.org/snippets/398/).

change settings locally in an individual test

So you need to change some settings when running an individual test in a test case. You could just wrap the test between `old_value = settings.MY_SETTING` and `settings.MY_SETTING = old_value`. This snippet provides a helper which makes this a bit more convenient, since settings are restored to their old values automatically. Example usage: class MyTestCase(TestCase): def test_something(self): with patch_settings(MY_SETTING='my value', OTHER_SETTING='other value'): do_my_test()

manage.py for eclipse with pydev debugging

This code is referenced in a [screencast](http://blog.vlku.com/index.php/2009/06/10/djangoeclipse-with-code-complete-screencast/) focused on showing a user how to configure Eclipse with PyDev to give you code complete, and breakpoints inside the IDE. It comes from a [2007 blog post](http://bear330.wordpress.com/2007/10/30/how-to-debug-django- web-application-with-autoreload/) (I've replicated it in case that post ever disappears.)

One step up from __icontains

The [REGEX and IREGEX](http://docs.djangoproject.com/en/dev/ref/models/querysets/#iregex) operators were added in Django 1.0 and I'm sure you can think of fancier ways of doing word delimiting and things like that but this was all I needed to make a user-friendly autocomplete search function.

superSearch function for generating large OR queries

superSearch is intended to make it easier to make complex OR queries, thusly hitting the database less. EXAMPLE: Searching for a user named 'Eric Neuman' would be difficult because first_name and last_name are separate fields. However, with superSearch, it's a breeze. query = ['Eric Neuman'] f = ['first_name','last_name'] s = query.split(' ') m = ['icontains'] results = superSearch(User, f, m,s)

Query lookups using operators

This class emulates query lookups to behave as numeric operators. Inspired by SQLAlchemy. User.objects.filter( X('username') == 'diverman' ) User.objects.filter( X('username') != 'diverman' ) User.objects.filter( X('pk') > 10 ) User.objects.filter( X('pk') >= 10 ) User.objects.filter( X('pk') < 10 ) User.objects.filter( X('pk') <= 10 ) User.objects.filter( X('username') % 'iverma' ) User.objects.filter( X('username') << 'diver' ) User.objects.filter( X('username') >> 'man' ) User.objects.filter( X('pk') | (1, 2, 3) )

Database cleanup

***About*** I tried to dump data from my database (manage.py dumpdata) and I couldn't do it because of error: User matching query does not exists I found out that my database was filled with garbage: entries those foreigners were deleted. My table's engine is MyISAM so it allows for these lost entries to exist. I had to cleanup my database before I do datadump, so I've written a script which worked fine for me. ***Usage*** Place this script in same directory with your settings.py and run it: `python db_cleanup.py` ***Disclaimer*** Backup your data :)

integrated jinja2 which could use generic view ,my djangojinja2.py

I tried a few snippets of integrated jinja2 in django, which provided ?.render_to_string and ?.render_to_response in the way of jinja2. **But those snippets could not use the generic view**, because of the generic views is use default django template. so i write this snippet which could use generic view, and use the basic django.shortcuts.render_to_string, django.shortcuts.render_to_string. #in yourproject/urls.py : #install default environment is very simple djangojinja2.install() #install environment of specified Environment class from jinja2.sandbox import SandboxedEnvironment djangojinja2.install(SandboxedEnvironment) #alternative you can install sepcified environment env=Environment(...) ... djangojinja2.install(env) #something could be set in settings.py TEMPLATE_DIRS = (path.join(path.dirname(__file__),"templates"),) JINJA_GLOBALS=['myapp.myutil.foo',] JINJA_FILTERS=['django.template.defaultfilters.date',] JINJA_TESTS=('foo.mytest',) JINJA_EXTS=['jinja2.ext.i18n'] #there is no change need for app.views from django.shortcuts import render_to_response def foo(request): return render_to_response('/myjinja2.html',{'request':request}) test in django development version of r12026 , jinja2 2.2.1, python 2.5

slug_and_slash_to_dash - modified slugify for urls

This filter converts slashes to spaces in a a sting and then slugify's the result. However, it ignores leading and trailing slashes. For example, it can take something like this: /some/url/with-an-existing-slug/ And turn it into this: some-url-with-an-existing-slug The filter was originally written to use the *curent* url as the `disqus_identifier` for Disqus comments. For example: {{ request.META.PATH_INFO|slug_and_slash_to_dash }}
